I'm a marketer and want have give out promotional codes offline to offer different audiences discounts when they purchase a course through the app store. the courses we offer are not on a subscription basis. The courses are a 1 time download. Can i give out codes to potential customers that they can redeem when they pay for the course in the app? i.e sign up today use code x and get y off your purchase at checkout .if this is doable any help on how we do this would be great . thanks

is there an Apple-supported way to offer discounts on in-app purchases that are not subscriptions? If so how can this be done?

I have a website that has been built in Wordpress and hosted on wordpress engine. In testing now and on the i phone with safari browser it keeps crashing after short time 2/3 minutes, content does not display properly pages go blank etc. Has anyone experienced this /have a solution? Thanks
